Quasisteady Viscous Flows.

Abstract

In earlier work the author has applied quasisteady analysis to inviscid atmospheric flow. The goal of such analysis is to obtain simplified mathematical models which are consistent with both the original model and the physical scale of the problem. In the present paper this approach is applied to time-dependent viscous flows. The basic model consists of Cauchy's Equations in which relaxation equations are used to model the viscous parameters. Quasisteady models are obtained for the one and two dimensional cases, and specific application is made to both compressible and incompressible boundary layer situations. Several analytical and numerical solutions are obtained for the incompressible models. (Author)
